Abstract

Background: Usefulness of left atrial (LA) strain measurements using speckle tracking echocardiography has been reported in various clinical settings. However, clinical implication of routine LA strain measurements in daily practice remains unclear. The purpose of this study was to evaluate clinical utility of routine LA strain measurements in daily practice.

Methods: From January 6, 2020 to December 28, 2021, 338 consecutive patients underwent echocardiography in Takagi Cardiology Clinic, and all comers were enrolled to the study. Echocardiographic measurements including peak atrial longitudinal strain (PALS) measurement using speckle tracking echocardiography were attempted in all patients.

Results: PALS was obtained in 335 patients (age 71 ± 16 years, male 43%, hypertensive 74%), and mean value was 22.3 ± 11.5%. PALS was progressively impaired with worsening atrial fibrillation (AF) burden. PALS in patients without AF, in patients with history of AF (paroxysmal AF &/or ablation therapy), and in patients with AF onsite were 26.8 ± 9.8%, 20.3 ± 7.9%, and 8.1 ± 3.3%, respectively (anova p < 0.0001). In patients without history of AF at the time of echocardiography, using cut-off value of 15.0% (i.e., mean + 2SD of PALS in AF patients), Kaplan-Meier analysis revealed that impaired PALS was associated with increased new-onset AF during follow-up period (log-rank p < 0.0001).

Conclusion: In daily practice, PALS represents AF burden. Furthermore, impaired PALS is associated with increased new-onset AF. Therefore, routine LA strain measurements using speckle tracking echocardiography will be useful in risk stratification of AF in daily practice.

峰值心房纵向应变代表心房颤动负担在日常实践:常规左心房应变测量的临床意义。

背景:利用斑点跟踪超声心动图测量左心房(LA)应变的有效性已在各种临床环境中得到报道。然而，在日常实践中常规LA应变测量的临床意义尚不清楚。本研究的目的是评估常规LA应变测量在日常实践中的临床应用。方法:2020年1月6日至2021年12月28日，在高木心脏病诊所连续338例患者接受超声心动图检查，所有患者均纳入研究。超声心动图测量包括使用散斑跟踪超声心动图测量心房纵应变峰值(PALS)。结果:335例患者获得PALS，其中年龄71±16岁，男性43%，高血压患者74%，平均22.3±11.5%。随着房颤(AF)负担的加重，PALS逐渐受损。无房颤患者、有房颤病史(阵发性房颤和/或消融治疗)患者和房颤现场患者的PALS分别为26.8±9.8%、20.3±7.9%和8.1±3.3%(方差分析)结论:在日常实践中，PALS代表房颤负担。此外，pal受损与新发房颤的增加有关。因此，在日常实践中，使用斑点跟踪超声心动图进行常规LA应变测量将有助于房颤的风险分层。
